Prevent costly false alarms and protect critical alarm devices with the Safety Technology International STI 1230NR Stopper II protective cover. Designed for security-focused facilities, this surface-mount security cover uses impact-resistant polycarbonate (PC) to shield fire alarm pull stations from accidental activations and vandalism while keeping controls fully visible for legitimate use. At roughly 5.4" H x 5" W x 5.2" D and featuring a supplied spacer, the cover installs quickly into existing boxes for fast retrofit projects.
